Dealing with a Trojan Horse on your PC or Mac computer can be a real challenge even to an experienced and knowledgeable user which is why most people get intimidated when they get (or think they have gotten) such a malicious program on their computer. This “fear factor” is something that a lot of online scammers use in order to trick their targeted victims to pay them money. Usually, it all goes something like this: a scam/phishing e-mail is send to the targeted user in which it is stated that the user’s machine has been compromised by a dangerous Trojan virus and that if a ransom isn’t paid to the hacker, they’d use the malware to damage the system of the PC or publish online some sensitive private information about the user. Normally, a BitCoin wallet is linked in the e-mail which is where the users are supposed to pay the money.

Of course, receiving such a message is likely to startle the majority of users – especially the ones who are not too experienced or the ones that are more naive. Regardless, if you are reading this and have been a target of such a phishing e-mail scam, then remember that paying the requested money is not the advisable course of action. In many cases, the statements about a virus in your system are nothing but a bluff and there’s really not anything wrong with your machine. Still, it is very important that you check your system for anything suspicious and potentially dangerous. Recently, a nasty Trojan virus known as TooltabExtension.dll has been attacking the computers of many users so it might be worth it to see if your computer doesn’t have it, just in case. That is also why we have posted our TooltabExtension.dll removal guide below which you can use at any time to clean your computer in case you have this malware.

  • Remember this step – if you have reason to believe a bigger threat (like ransomware) is on your PC, check everything here.

Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

Do not panic!

As we already stated, the fact that you have received such an e-mail message absolutely doesn’t mean that the scammers/hackers do indeed have unauthorized access to your system and data. It is really important that you do not fall into their trap and send them the money.

However, since Trojans are still a significant malware threat that is oftentimes difficult to notice and detect, using our guide and/or the removal tool for malware that’s in it is highly advisable. Also keep in mind that Trojans can be distributed in all sorts of ways – through spam messages, malicious web advertisements, contaminated software downloads, pirated programs and many more.

Trojans can harm their victims in many ways and cause all types of issues like data corruption and HDD formatting, backdooring of Ransomware and Spyware infections, espionage and so on and that is why you can never let your guard down when it comes to cyber security.
